ACKNOWLEDGEMENTS

Appreciation is expressed to the cooperators who provided their land, equipment, and time in assisting

for preparation, planting, field management, and harvesting of these plots throughout the year. All

cooperators are listed in Table 3. We would like to extend our appreciation to Cotton Incorporated

through the Texas State Support Committee, Americot/NexGen, Bayer CropScience, Delta Pine, and

Phytogen Cottonseed for their partial funding of these trials.

2016 HIGHLIGHT

Variety selection is the most important decision made during the year. Unlike herbicide or insecticide

decisions that can be changed during the season to address specific conditions and pests, variety

selection is made only once, and variety selection dictates the management of a field for the entire

season. Variety decisions should be based on genetics first and transgenic technology second. Attention

should be focused on agronomic characteristics such as yield, maturity, and fiber quality when selecting

varieties. To assist Texas cotton producers in remaining competitive in the Rolling Plains, the Texas A&M

AgriLife Extension Service Agronomy program has been conducting, large plot, on-farm, replicated

variety trials since 2012. This approach provides a good foundation of information that can be utilized to

assist farmers with the variety selection process. The results from

the RACE trial are summarized in the Table 7 – Table 19.

Figure 1. The 2016 RACE trial locations in the Rolling Plains of Texas. Red stars represent irrigated

trials, while orange stars represent dryland trials.

The RACE trials were planted in 14 locations across the Rolling Plains in 2016, of which 13 locations were

harvested. Planting dates ranged from May 10th to June 14th, while the harvesting dates ranged from

November 10th to January 13 in 2017. Mean location yields for the 2016 RACE trials in the Rolling Plains

ranged from 797 lb/ac (Haskell Co.) to 1974 lb/ac (Collingsworth Co.) in the irrigated sites and from 409

lb/ac (Kent Co.) to 1574 lb/ac (Haskell Co.) in the dryland sites. Average lint yields across all locations

were 1209 lb/ac in irrigated sites and 930 lb/ac in dryland sites. Average yield across locations were 375

lb/ac less in irrigated and 346 lb/ac more in dryland sites than 2015 growing season.

Tables 7-19 include the RACE trial yield data and fiber analysis for each individual location. Data featured

in these tables include: statistical analysis of yield, turnout, fiber quality parameters, loan and gross lint

value/acre. Most locations were ginned with a 20-saw table-top gin with no lint cleaner. This method

consistently produces higher lint turnout percentages than would be common in a commercial gin.

Consequently, higher turnouts equate to lint yields which are generally higher than area-wide

commercial yields. The statistical analysis quantifies the variability of the test site conditions, such as soil

type, harvesting, insect damage, etc. A CV (coefficient of variation) of 15% or less is generally considered

acceptable and means the data are dependable. Values with same lower case letters (for example, a, b,

and c) within a column are not statistically different at a 90% confidence level. Lint values were

calculated using the 2016 Upland Cotton Loan Valuation Model from Cotton Incorporated.

Table 2. FIBER EVALUATION

Parameters Definition Degrees

Micronaire (Mic) Micornaire is a measurement of both fiber fineness and maturity.

Premium range: 3.7-4.2 Base range: 3.5-3.6 or 4.3-4.9 Discount range: 0-3.4 or >5.0

Fiber length The average length of the longer half of the fibers.

Extra-long: >1.26 Long: 1.11-1.26 Medium: 0.99-1.10 Short: <0.99

Fiber strength Fiber strength as measured on the High Volume Instrument is the force in grams required to break a bundle of fibers one tex unit in mass.

Very strong: > 31 Strong: 29-30 Average: 26-28 Intermediate: 24-25 Weak: < 23

Length uniformity (unif)

Length uniformity index is the ratio between the “mean length” of the fibers and the “upper half mean length”.

Very high: >85 High: 83-85 Intermediate: 80-82 Low: 77-79 Very low: <77
